How to solve x y = 2 x 2 + y 2 + y?
And what would be the standard form to illustrate this situation? (e.g. y + P ( x ) y = Q ( x ) would be standard form of first order linear differential equation)

The l g function is the logarithm to the base 2 (or binary logarithm), that is, l g 2 = 1. Thus
l g ( i + i ) = l g ( 2 i ) = l g 2 + l g i = 1 + l g i
By the way, the l g function can also be defined by l g ( x ) = log x log 2 .

How to construct an exact but non separable differential equation?
So I can prove that all separable differential equations are exact, and I can intuitively figure out that not all exact differential equations are necessarily separable, but I'm having a hard time constructing a counterexample?
Is a differential equation still considered inseparable if you cannot initially separate it, but do so using an integrating factor?
Sorry for asking rudimentary questions, I'm just starting to learn diff eq's.
Thank you in advance.

When linear differential equation can also directly be solved by variable separable method?
Consider the linear differential equation d y d x + p ( x ) y = q ( x ) . 1. What conditions may be imposed on functions p ( x ) and/or q ( x ) so that it could directly be solved by variable separable method rather than integrating factor e p ( x ) d x . 2. In the case if it can be solved by both variable separable and integrating factor method, which would be more suitable?

Separable Differential Equation explained
So i have the equation d y d t = 1 + y
looking at the answers my lecture has given it states
d d t ( 1 + y ) = 1 + y
then 1 + y ( t ) = A e t where A is a constant
Can someone explain these steps please?

Differential Equation
solve differential equation
d y d x = ( 3 x y 6 ) ( x + y + 2 )
I tried to do this but it´s first order and posible is separable variables

Solve this separable differential equation
How would I go about solving the following separable differential equation?
d x ( t ) d t = 8 3 x with x ( 0 ) = 4?
My solution thus far is the following:
d x ( t ) 8 3 x = d t + C
ln | 8 3 x ( t ) | = 3 ( t + C )
Now using the fact that x ( 0 ) = 4 we can solve for C = 1 3 ln | 4 | . From this, I would seem to get
| 8 3 x ( t ) | = e 3 t 1 3 ln 4
but something seems to go wrong. Am I making a mistake somewhere and how could I solve this entirely?
